The invention discloses a reinforced concrete support axial force calculation method considering creep influence. The reinforced concrete support axial force calculation method comprises the following steps: 1, determining physical and mechanical parameters of a concrete support; 2, when the reinforcement effect is ignored, calculating a concrete creep coefficient; 3, calculating a concrete equivalent creep coefficient while considering the reinforcement effect; 4, calculating the average strain value of the cross section of the concrete support member for eliminating the creep influence by actually measuring the frequency value of the sensor; and 5, establishing a support axial force calculation equation through a concrete stress-strain relationship. Compared with an existing concrete support axial force calculation method, the method has the advantages that the influence of the creep effect on the reinforced concrete support axial force can be effectively eliminated, and a real reinforced concrete support a
